⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal administrator session cookies, perform actions as the administrator (like installing backdoors or creating new admin accounts), or redirect users to malicious sites.
Likely Case
Attackers would typically use this to steal session cookies or credentials from administrators who click on crafted links, potentially leading to site compromise.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be rendered harmless as text rather than executable code.
🎯 Exploit Status
The vulnerability requires user interaction (admin clicking a malicious link) but is trivial to exploit once the link is crafted.
